joel explains that cuba has two currencies. the cuban peso used every day by the vast majority of cubans, and the convertible peso used often by foreign tourists to buy luxury goods. he says on a good day, he can make 1100 regular pesos but figuring fuel costs and the exchange rate, he is down to 10 paces and convertible profits. that's about 10 u.s. dollars, which means to make a living, joel drives about 14 hours a day, six days a week. still, he is proud of his work and his car. >> it's a rolling museum. in other countries, these cars are seen as hobby, as classics people keep for their own pleasure. here, it's our means of transport, our work, and our income. thanks to these old american cars, we have work. the cars are sturdy. they are the only ones that would last as long.
